Hi,
I've been testing the leds with the BCD3000 on linux this morning. The code
in the xml file for a test led is:
<lights>
<light>
<group>[Channel1]</group>
<key>play</key>
<status>0x7F</status>
<midino>0x12</midino>
<threshold>0.5</threshold>
</light>
</lights>
However, when I try to load a song on Deck A, mixxx crashes. I send below
the last messages I see on the terminal where mixxx was running. If I
comment out the lights code shown above, mixxx runs fine and I can control
it using the BCD3000 (without the leds working). Any idea?
